This invention relates to plumbing xtures and in particular to thearrangement of the water supply thereof in relation to the waterretaining compartment and overow chamber.

In plumbing xtures the water supply pipe is generally located over andtoward the rear of the water retaining compartment. When the wat/ersupply is shut ofi", water remaining in and near the end of the supplypipe drips into the water retaining compartment. Water also drips fromthe supply pipe into the Water retaining compartment of plumbingfixtures because of leaky valves in the supply lines.

The ldripping of water into the water retain- 5 ing compartment ofplumbing fixtures is generally undesirable for two major reasons. First,the constant drip, drip, drip creates an undesirable sound which annoyspeople in the room, in rooms adjacent to, or within hearing of the if'room in which the plumbing fixture is located.

Second, in communities in which the domestic water supply contains ironand the like, the dripping of water into the Water retaining compartmentof plumbing xtures causes localized and unsightly stains on the enamelin regions directly under the water supply pipe. Also, in some fixtures,hard Water from leaky valves runs from the supply down one side of theWater retaining compartment thereof and causes unsightly streaky stainsthereon.

The main object of this invention is to provide a drip proof plumbingfixture.

Another object of this invention is to provide a plumbing xture having awater supply in connection therewith which is so located as to directwater under pressure being discharged therefrom into the water retainingcompartment oi the said fixture and to permit water dripping from saidwater supply to run down the inside of an overflow chamber.

Another object of this invention is to provide a plumbing fixture havinga water retaining compartment and an overflow chamber in combinationwith a water supply concealed from View in a communicating overflowaperture between the said water retaining compartment and the overiiowchamber, the said water supply being so located as to direct water underpressure being discharged therefrom into the water retaining compartmentof the said fixture, the wall of the Water retaining compartmentdirectly below the overow aperture being so formed as to direct Waterdripping from the said Water supply into the inside of the said overflowchamber.

Yshowing a lavatory embodying this invention.

This invention may be applied to other lavatory constructions known tothose familiar with or skilled in the art, and may be readily applied tobath tubs, foot baths, kitchen sinks,

laun tubs and the like; such use and applij;

cation of this invention is intended to be broadlv within the scopehereof.

Referring particularly to the drawing, the embodiment sho-wn thereincomprises a lavatory ill having preferably integral vertical back splashshield il at the top of which the horizontally disposed top portion i2and at the sides of which the extended vertical sidesr iS retain thelavatory and splash shield at the desired distance from the wall il andat the same time enclose the rough piping from view. The top portion i2is turned down at its rear side to form a vertically disposed .strip i5by which the lavatory is supported from the Wall lli by any suitablemeans such as the clips il and lag screws ill. The extended verticalsides i3 are preferably turned in to form a bearing strip l along thewall ill.

The lavatory is provided with a water retaining compartment li! havingan overflow aperture Eil formed in the rear thereof at the proper heightto permit water, after attaining a predetermined depth in the waterretaining compartment, to overflow into an overflow chamber 2|. A drain2?. is located at the bottom of the Water retaining compartment and maybe closed by any desired type of stopper or stopping mechanism, notshown. Both the overflow chamber 2l and the drain 22 are preferablyconnected to a trap, not shown, through which surplus water and wastefrom the lavatory pass before entering a soil pipe which preferablycarries the said Water to a sanitary sewage system.

in forming the overflow aperture 2li, a lip 23 is preferably turnedbackward from the rear of the water retaining compartment I9 tolap overthe forward wall of the overflow chamber 2l. A shield 25 is formed infront of and over the said overflow aperture 2t to conceal it from View.

The rough hot and cold water pipes 25 and 26 lead to two valves 21having operating handles 28 by means of which water is admitted andmixed in the desired quantity and to the required temperature in supplypipe 29 from whence it is discharged under pressure into the waterretaining compartment i9.

The supply pipe may be held in its proper location in respect to theoverow aperture 2G, the lip 23 and the shield 2d by such means as awasher 39 and a nut Si and a washer 32 and a nut 33 of each valve 2?which engage the splash shield l i, proper holes having been formed inthe said splash shield ll through which the stem ends of the valves 2protrude.

The end of the supply pipe 29 is so shaped and located in respect to theoverflow aperture 20 and the lip 23 that water supplied under pressurethrough the supply pipe 29 will discharge into the water retainingcompartment I9 and water dripping from the said supply pipe 29 will dripinto the overflow chamber 2l preferably via the rearward end of the lip23 and down'the inside of the forward wall of the overilow chamber 2l.

The overflow chamber 2| may be three sided or semi-circular in shape andwelded to the black of the rear of the water retaining compartment, ormay be cast integral therewith, in which event the end of the lip '.23would be brought around to substantially meet the back of the rear wallof the water retaining compartment which would serve as one wall of theoverflow chamber. It is important to prevent dripping within the overowcompartment which may be and is accomplished by the proper shape of thelip 23 in respect to the inside wall of the overflow chamber 2l.

Although only one form land embodiment of this invention has beendisclosed and described in detail, it will be apparent tothose skilledin the art that various details thereof may be changed and manymodifications made without departing from the scope of the appendedclaims.

I claim:

l. In combination with a plumbing xture comprising a water retainingcompartment and an overow chamber having a communicating overflowaperture therebetween, a supply pipe having its discharge end so shapedand located in respect to said overow aperture that water supplied underpressure through said supply pipe will discharge into said waterretaining compartment and water dripping from said supply pipe will dripinto said overflow chamber.

2. In a plumbing fixture, a water retaining compartment, an overflowchamber adjacent to :said water retaining compartment, the said waterretainingcompartment having an overflow aperture formed in a Wallthereof, a curved lip formed in said wall directly below said overflowaperture, the end or said curved lip being in juxtaposition to theinside wall of said overflow chamber, and a supply pipe having itsdischarge end so shaped and located in respect to said overflow apertureand curved lip that water supplied under pressure through said supplypipe will discharge into said water retaining compartment and waterdripping from said supply pipe will drip on said curved lip and flowdown the inside wall of the said overflow chamber.

3. in combination, a plumbing fixture having a water retainingcompartment and an overflow chamber adjacent thereto, the said waterretaining compartment having overflow aperture formed therein, a supplypipe having its discharge so shaped and located in the respect to saidoverflow aperture that water supplied under pressure through said supplypipe will discharge into said water retaining compartment and waterdripping from said supply pipe will drip into said overow chamber, andmeans for directing water dripping from said supply pipe into theoverflow chamber and down one Wall of said overflow chamber.
